I single hand my 26S most of the time and what I do depends on my setup somewhat. I have a 110 furling jib so the jib sheets are on the top of the cabin on each side of the companionway. I also have a windward sheeting traveler.
When single handing, I sit forward on the seats because my traveler gets a lot of use. In order to sit forward, you need a tiller extension.
You also need some way to hold the tiller in a fixed position and there are a variety of ways to do this.. My tiller extension is telescoping with a ball on the end and I have a "socket" on the companionway lid that the ball fits into so I can hold the tiller in any position. Take a look also at a tiller clutch or a tiller tamer.
There is a technique called "heaving to" that you should definitely google and study then practice. Heave to works well at least on my setup (same boat as the OP). Heave to involves the jib, centerboard and rudder leaving the main sail "free" while the boat drifts at maybe 1.5 knots or less. Very useful for single handing.
I think sailing the boat is fairly straight forward.. with the tiller extension you have access to all the controls (in my case jib sheets, main sheet, traveler, vang, outhaul and back stay tension). Some techniques for the other stuff you will have to do..
Initial raising / setting up the main - with the outboard running and in gear (and no jib yet), get the boat going straight into the wind and lock the tiller. You will have some time to go forward for setting up the main. Some people like the halyards and reefing lines led back to the cockpit. I just prefer to do up to the mast for both setting up the main sail and reefing it. Having the outboard running will normally give you more time before the boat starts to drift off from straight into the wind. It may take a couple of iterations of setting the boat into the wind and messing with the main to get it set up correctly.
An alternate to this that I have only tried once in fairly high wind. Put the jib up first and get the boat in heave to. Someone will tell you that this cant be done without the main.. but I have actually done it. With the boat in heave to and drifting slightly, set up the main.
For reefing the main or shaking out a reef on the main - put the boat in heave to. The main sheet will be loose and its a fairly relaxed process to now go deal with the main sail as the boat is slowly drifting.
Dropping the main - either put the boat in heave to with the jib up then drop the main or furl the jib, start the outboard, put the boat in gear and pointed into the wind.. just the opposite of setup.
Couple pictures below.. I moved my tiller extension to the very end of the tiller this season for max leverage. The extension is telescopic with a ball / socket so I can set the length, twist lock it for any tiller position. See tiller clutch also.
picture below - Since I have a 110 jib, the jib sheet cleat on the port side can be seen in the picture below and I really like those "extreme angle" fairleads for the cam cleats. Reason is that you are often sitting on the upwind side of the boat but the jib sheet you may need to control is on the downwind side of the boat. Not completely perfect.. but I think a nice addition for single handing. FYI, you really dont need the winch for the 110 jib.. Two cleat in that picture, one is the jib sheet, the other is the vang.
